SAMUEL PEARL, OF NEW YORK, N. Y.

SAFETY-PIN.

Specification of Letters Patent.

Patented Aug. 25, 1908.

Application filed my 18, 1907. Serial No. 374,480.

Toullwhom it may concern: I Be it known that I, SAMUEL PEARL, a citiion of the United States, residing at the bor oiigh'of Manhattan, city, county, and State of New York, have invented new and useful Improvements in Safety-Pins, of which the following is a specification.

My present invention has for its object to overcome the bending of the pmbars of safety pins by providing improved means for jected to considerable strain and to hold the pin bar end in the shield or guard so that it cannot be released by a hard pull upon the pin, whereby the full strength of the wire is obtained.

In the drawing, Figure 1 is a side elevation of a safety pin embodying my invention,

with the pointed. member of the pin released y from the shield or guard. Fig. 2 is also a side 1 elevation of such pin partly in section, with the pointed member secured in the shield or guard. Fig. 3 is a side elevation, showing the manner in which the pointed member of the pin is securely locke d and held in the shield or guard when the pin is subjected to considerable strain, and Fig. 4 is a cross section on the'li'ne ca, 00, Fig. 2.

' My invention comprises in combination with the pointed pin bar A, the spring coil F and integral wire member G, and a shield 13 to which said parts are secured at the free end of the member G, a bent portion C formed in the pin bar A at a predetermined distance from the point and in the plane of the safety in; a catch or hook D formed in and from the shield by bending over or downward the edge thereof against which the pin bar A bears when in place, and a lug E formed from or secured to the body of the shield at the inner central portion thereof. The shield or guard B is preferably of the type closed on one side and its edge at the open side is bent as shown and overturned on the free end of the wire member G.

When the pointed end. of the pinbarA is inserted in the shield or guard B, the catch or hook D engages the indentation C on the upper surface of the pin bar A, thus securing shield r guard B when the pin is subjectedv to unusual strain, is overcome to a large extent, but to lock the pin bar A in the shield or guard positively and securely against any possibility of withdrawal by extraordinary strain, I make use of the lug E which coacts with the hook D and indentation C to accomplish this purpose. the inner side of the shield or guard B arid may be an integral part of the shield. I have shown a part of theshield cut out and bent inward to form the lug E.

When the pin is in use, the bar A is held firmly in the shield or guard B by means of the downwardly bent end of the shield forming the hook D engaging in the indentation C on the pin bar A, and by this means the pin will withstand considerable strain without the point being withdrawn from the shield, but should the pin be subjected to undue strain, its tendency to bend or bow outward and the point to be tipped toward the center of the shield and so gradually withdraw from the shield, will be overcome by means of the lug E, which under such circumstances, forms a stop under the movable pin bar A at a predetermined distance from its pointed end, by which means the movable pin bar A is locked securely between the'two bearing points.

The indentation C on the pointed member being made by bending'the wire,.does not weaken the same but leaves a smooth sur-' face, so that there is no she edge to tear or injure the article upon whic 1 the pin is employed, and it will also be seen, by reference to Fig. 3, that the pointed end of the pin does not come into contact with anything to dull or injure it when the pin is subjected to extraordinary strain.

I claim as my invention;

1. A safety pin comprising a wire member, spring end, a pin-bar having a bend in it at a predetermined distance from its point forming a recess or indentation, a shield with an over-turned edge to engage the said indentation in the connected relation of the parts, and a lug upon the inner surface of the shield coming below the pin-bar and acting as a lock under excessive strain.

2. A safety pin comprising a wire member, spring end, a pin-bar having a bend in it at a predetermined distance from its oint forming a recess or indentation 1 'ng 1n the plane of the safety pin, a shield aving an overturned edge to engage the said indentation in the connected relation of the parts, and a lug upon the inner surface of the shield coming below the pin-bar at a predetermined The lug E projects from I distance from its point and acting as a lock to excessive strain to securely lock the pinunder excessive strain. I bar within the shield.

3. A safety pin comprising Mixed member, In testimony whereof, I, SAMUEL PEARL spring- (Ind and pin-bin" all of a single piece have signed my name to this specification 5 st wire, a ishield at the end of the fixed 1n01'n. in the presence of two subscribing witnesses. 15
